Add an inline filter to fridge
I have an older Admiral fridge that is working well. I need to add a filter (pre-dates built in inline filters). I have copper tubing from the water source and then some plastic tubing running up the back of the fridge. Am I correct in assuming that this is the water line? Where do I go from here once I have the filter. Online directions are a bitg confusing as they refer to both copper and plastic water lines.
I know I sound dumb, but I've accomplished quite a few things DIY with advice from these forums. Help me out. Please.
